That little wooden area in a liquor case (usually in a grocery store like Safeway) between the transparent glass panels that it is nigh impossible to see or notice the bottles behind, causing the clerk to search the area around it like a madman while the bottle the customer wants is just out of immediate sight. Thankfully, most of the more commonly sought-after bottles are not there. Unless they want Bailey's Irish cream in half-gallons. That shit is always in that space.
